I want to install my VMlite XP Mode new, with the updated VirtualBox Version 4.0.8.
So I installed first the VirtualBox and than tried to install VMLite plugin 3.1.2.
The wizard of the plugin is telling me every time, that I must first install VirtualBox, what I had done several times.

Can it be, that the plugin is only working with the old VirtualBox version 3.1.2?
If so how can I install now the VMLite XP-Mode with VirtualBox 4.0.8 with the plugin V3.1.2?

Funny that you mention that, I had run into the same issue a few days ago. My guess is that it's an installer/compatibility issue.

I'm hoping a plug-in that works with VirtualBox 4 is coming soon and would be interested in even test driving a beta (hint hint ). Reading this post has my hopes up for the time being.

I use VirtualBox to run a 64bit Linux sandbox/dev environment and wanted to run XP mode to test different versions of IE and other apps on XP and ran into issues with Windows Virtual PC not being able to run since VirtualBox was already running a vm with h/w acceleration (VT-x/AMD-v). Nothing like watching 2 virtual host apps fight for resources.

Scouring the web I found VMLite XP Mode and it looked like a good solution to use the two together. I like VirtualBox because it feels more "light weight" in comparison to VMware Server. I would have went with Windows Virtual PC, but it had no support for 64bit systems, which I find to be odd.

I'm stuck in this silly loop as well. I speculate that they are looking in the Registry for "Sun VirtualBox" instead of "Oracle VirtualBox" and so the fix is pretty easy, but that's only a guess. Could we please have some official word from the VMLite folks?
